Hi Alois,
Hi Zakaria,
Perhaps you are a little bit unbalanced in your ready position. Try to get the weight more onto the front of your foot rather than the back. As you are moving try to keep your weight down lower. If you come up you may throw your balance out.
Keep awareness on this balance and you will be able to adjust it.
